为什么这不是循环？ Python 2.7

视窗7

当我键入一次“播放”时：

它做它应该做的事。当我输入“play”两次错误时，它不是循环而是退出。在谷歌上搜索，但什么也找不到：/

代码：

看看你的代码：

def startg():
game = raw_input("Type 'Play' to start. ")
if(game == "Play"):
 print("Loading. . . ")
 playg()

if(game == "play"):
print("Make sure you type 'Play', CaPS MaTteR! ")
startg()
elif(game == "Play"):
playg()

如果第一次输入Play时出错，会发生什么情况？好吧，它去了startg。有条件的ifgame==Play，但是除了正确的输入之外，没有其他语句来处理任何事情。因此，如果第二次键入play，则会导致程序无法解释的情况。因此，不调用任何函数，程序将一直进行到最后

顺便说一下，您应该引入一个else语句来处理以其他方式拼写错误的所有情况。不正确地大写并不是您应该准备处理的唯一潜在错误

我就知道会很简单，谢谢！c:

name = raw_input("What is your name? ")
gender = raw_input("What are you, a Boy or a Girl? ")
print(" ")

if(gender == "Boy"):
their = "his "
else:
their = "her "

game = raw_input("Type 'Play' to start. ")

def endg():
print("Hope you had fun! ~Red")

def startg():
game = raw_input("Type 'Play' to start. ")
if(game == "Play"):
 print("Loading. . . ")
 playg()

listq1 = ["A. Quit your job." , "B. Pretend you never saw the stack of papers." , "C.             Kill yourself because you don't feel like playing this game. "]

def playg():
answer = raw_input("You are a programmer, " + name  + ", who hates " + their + "job     very much." +
      " You walk into work to see a huge stack of papers on your desk... What do you     do? \n" + "\n".join(listq1))
if(answer == "A"):
    print("\nYou look around the room and see the flock of miserable people...Your     Co-Workers.  Is working here really worth the stress? ")
elif(answer == "B"):
    print("\nYou pull the over-sized recycle bin out from under your desk.  Just as you start to slide the papers to their impending doom, a fellow co-worker stops to ask what you are doing. ")
elif(answer == "C"):
    endg()

if(game == "play"):
print("Make sure you type 'Play', CaPS MaTteR! ")
startg()
elif(game == "Play"):
playg()

def startg():
game = raw_input("Type 'Play' to start. ")
if(game == "Play"):
 print("Loading. . . ")
 playg()

if(game == "play"):
print("Make sure you type 'Play', CaPS MaTteR! ")
startg()
elif(game == "Play"):
playg()
